Parts shall not become detached, and they shall remain in the locked position.
21.23 Handles, knobs, grips, levers and the like shall be fixed in a reliable manner so that they will not
work loose in normal use, if loosening might result in a hazard.
Compliance is checked by inspection, by manual test, and by trying to remove the handle, knob, grip or
lever applying, for 1 min, a 30 N axial force either pushing or pulling.
21.24 Storage hooks and similar devices for flexible cords shall be smooth and well rounded.
Compliance is checked by inspection.
21.25 Current-carrying parts and other parts, the corrosion of which might result in a hazard, shall be
resistant to corrosion under normal conditions of use. Stainless steel and similar corrosion-resistant alloys
and plated steel are considered to be satisfactory for the purpose of this requirement.
Compliance is checked by verifying that after the tests of clause 18, the relevant parts show no sign of
corrosion.
NOTE Examples for causes of corrosion are the incompatibility of materials and effects of heating.

material is non-corrosive, non-hygroscopic, and non-combustible, such as glass-wool.
Compliance is checked by inspection, by the tests of clauses 16 and 17 and, if necessary, by chemical
tests or flammability tests.
